## Physics ch. Capacitance questions

Is it a scalar or a vector quantity? Electric potential. It is a scalar quantity. Is the potential difference positive, negative or zero, if Q is a positive b negative? Let the distance of points A and B from charge Q be and respectively. Find the work done in moving a charge of 10 mC between two diagonally opposite points on the square. As the two diagonally opposite points on the square are equidistant from the charge kept at the center, their potential is same, Therefore no work is done in moving the charge from one point to another.

Find the net capacitance of the capacitor? Here the two capacitors are in parallel Net capacitance. Prove that the energy stored in a parallel plate capacitor is given by? This work done is stored in the capacitor in the form of electrostatic potential energy. Using this theorem define an expression for the field intensity due to an infinite plane sheet of change of charge density? Keeping the voltage of the charging source constant.

## 3. Questions & Answers on Capacitance and Capacitors

It will give the students a proper theoretical explanation of this chapter, enabling the students to solve the questions by themselves. The critical questions list; questions which are often asked in the exams; is enlisted, described and explained comprehensively by the experts. This chapter's important topics are more or less, the introduction to electrostatic potential and capacitance, Dielectrics and polarisation, the potential energy of a system charge, the relationship between field and potential, etc. It will enable the students to understand the chapter entirely and allow them to solve question answers independently. Electrostatic potential.

What is the relation between current and voltage in a capacitor? If 2V is supplied to a 3F capacitor, calculate the chance stored in the capacitor. Answer: b Explanation: Q is directly proportional to V. The constant of proportionality in this case is C, that is, the capacitance. Calculate the current in the capacitor having 2V supply voltage and 3F capacitance in 2seconds. Answer: d Explanation: Q is directly proportional to V.
